Professor Gretta Pecl is Director of the Centre for Marine Socioecology and Professor of Climate Change Ecology at the Institute for Marine and Antarctic Studies. Gretta’s research has a particular focus on detecting and understanding the variation in rate and magnitude of climate-driven species redistribution. She developed and leads the very successful National citizen science project Redmap Australia, the Range Extension Database and mapping project (www.redmap.org.au), which invites fishers and divers around the coastline to help monitor changes in species distributions in Australian seas. She is the instigator and co-convenor of the ‘Species on the Move’ conference series (www.speciesonthemove.com), and is also currently working with international colleagues on a Global Network of Marine Hotspots to facilitate learning and communication among the world’s most rapidly warming ocean regions. Gretta is an Australian Research Council ‘Future Fellow’, the Editor-in-Chief of the journal Reviews in Fish Biology and Fisheries and an Associate Editor for Ecography and Citizen Science: Theory and Practice.
